A new [SSSS]-type bis(thiophenol) ligand based on a trans-cyclooctane-1,2- diyl(thio) platform was prepared by the reaction of trans-cyclooctane-1,2- dithiol with 2 mol equiv. of 3,5-di-tert-butyl-2- (2-cyanoethylthio)benzyl bromide followed by deprotection. The reactions of the [SSSS]-type ligand with [Pt(nb)(PPh3)2] (nb=norbornene) or [PtCl 2(PPh3)2] complexes produced unexpectedly a [sulfide-bis(thiolato)]-PPh3 PtII complex accompanying loss of one of the 2-sulfanylbenzyl groups. The structure of the PtII complex was determined by X-ray crystallography. The physical property and formation mechanism for the PtII complex are discussed.
